[HTML][HTML] The Eocene–Oligocene transition: a review of marine and terrestrial proxy data, models and model–data comparisons
Abstract The Eocene–Oligocene transition (EOT) was a climate shift from a largely ice-free
greenhouse world to an icehouse climate, involving the first major glaciation of Antarctica …

A paleolatitude calculator for paleoclimate studies
Realistic appraisal of paleoclimatic information obtained from a particular location requires
accurate knowledge of its paleolatitude defined relative to the Earth's spin-axis. This is …

Climate sensitivity, sea level and atmospheric carbon dioxide
Cenozoic temperature, sea level and CO2 covariations provide insights into climate
sensitivity to external forcings and sea-level sensitivity to climate change. Climate sensitivity …

Global cooling during the Eocene-Oligocene climate transition
About 34 million years ago, Earth's climate shifted from a relatively ice-free world to one with
glacial conditions on Antarctica characterized by substantial ice sheets. How Earth's …

Simulation of Eocene extreme warmth and high climate sensitivity through cloud feedbacks
The Early Eocene, a period of elevated atmospheric CO2 (> 1000 ppmv), is considered an
analog for future climate. Previous modeling attempts have been unable to reproduce major …

Eocene greenhouse climate revealed by coupled clumped isotope-Mg/Ca thermometry
Past greenhouse periods with elevated atmospheric CO2 were characterized by globally
warmer sea-surface temperatures (SST). However, the extent to which the high latitudes …
